Abstract

UNA TRACCION DE UN VEHICULO QUE INCLUYE UN SISTEMA DE CONTROL SOMETIDO A LA DEMANDA DEL OPERADOR, Y UNA TRANSMISION DE COEFICIENTE CONTINUAMENTE VARIABLE (CVT), INCLUYE UN MODIFICADOR DEL TIPO DE PAR CONTROLADO, EN EL CUAL EL SISTEMA DE CONTROL INCLUYE UN DIAGRAMA DE FUNCIONAMIENTO DE RELACIONES OPTIMAS ENTRE EL PAR MOTOR Y LA VELOCIDAD SOBRE UN MARGEN DE VALORES DE ESTAS DOS CANTIDADES, Y EN EL CUAL EL SISTEMA DE CONTROL REGULA LA ENTRADA DE ENERGIA A UN MOTOR Y TAMBIEN EL PAR DE REACCION EN EL MODIFICADOR PARA BUSCAR UN ESTADO EN EL QUE SE MANTIENE LA ACCION OPTIMA REPRESENTADA ENTRE EL PAR MOTOR Y LA VELOCIDAD. EL MODIFICADOR PUEDE SER DEL TIPO DE TRACCION GIRATORIA DE CARRERA TOROIDAL, SIENDO REGULADO EL PAR DE REACCION DENTRO DE EL CONTROLANDO LA FUERZA DE ACCIONAMIENTO APLICADA A LOS RODILLOS DEL MODIFICADOR. EL SISTEMA DE CONTROL PUEDE ACTUAR PARA CALCULAR EL PAR DE REACCION DEL MODIFICADOR CON RELACION A DOS CALCULOS ALTERNATIVOS BASADOS EN LOS PARES DE ENTRADA Y SALIDA DE TRANSMISION RESPECTIVAMENTE, Y PUEDE ELEGIR EL CALCULO, PARA EL ACCIONAMIENTO EN CUALQUIER MOMENTO DADO, CONSIGUIENDO EL MENOR VALOR DE ESE PAR DE REACCION DEL MODIFICADOR.A TRACTION OF A VEHICLE THAT INCLUDES A CONTROL SYSTEM SUBMITTED TO THE OPERATOR'S DEMAND, AND A CONTINUOUSLY VARIABLE COEFFICIENT TRANSMISSION (CVT), INCLUDES A MODIFIER OF THE CONTROLLED TORQUE TYPE, IN WHICH THE CONTROL SYSTEM INCLUDES A FUNCTION DIAGRAM OF OPTIMAL RELATIONSHIPS BETWEEN THE MOTOR TORQUE AND SPEED ON A VALUE MARGIN OF THESE TWO AMOUNTS, AND IN WHICH THE CONTROL SYSTEM REGULATES THE ENTRY OF ENERGY TO A MOTOR AND ALSO THE REACTION TORQUE IN THE MODIFIER TO FIND A STATE IN THE ONE THAT MAINTAINS THE OPTIMAL ACTION REPRESENTED BETWEEN THE MOTOR TORQUE AND THE SPEED. THE MODIFIER MAY BE OF THE TYPE OF TOROIDAL ROTATING TRACTION, WITH THE REACTION TORQUE INSIDE THE CONTROLLING THE DRIVE FORCE APPLIED TO THE ROLLERS OF THE MODIFIER. THE CONTROL SYSTEM CAN ACT TO CALCULATE THE MODIFIER'S REACTION TORQUE IN RELATION TO TWO ALTERNATIVE CALCULATIONS BASED ON THE TRANSMISSION INPUT AND OUTPUT PAIRS RESPECTIVELY, AND CAN CHOOSE THE CALCULATION AT ANY TIME GIVEN, WHICH IS AVAILABLE OF THAT REACTION TORQUE OF THE MODIFIER.
